Sinano DOSC010B ac servo drive

Sinano DOSC010B is an AC servo drive used to control industrial motor speed and position via PWM output and analog feedback. Common failure modes for this class of drives include power supply over‑voltage, capacitor degradation on the main board, overheating of the MOSFET array, and loss of communication with the controller due to broken I/O lines or firmware corruption. First‑check steps: verify that the input voltage is within spec and that the drive’s status LEDs indicate normal operation; inspect all power supply capacitors for bulging or leakage and confirm proper grounding; review any error codes displayed on the drive’s panel or communicated via Modbus/Profibus to identify specific fault conditions.[oss-gpt-20b]
